Answer
A strong electrolyte is a solution/solute that completely, or almost completely dissociates or ionize in solution.
Acetic is a weak electrolyte because it does not completely dissociates in solution.
So given statement is False.
Add Answer to:
Acetic acid, ammonia and water are best described as strong electrolytes. Select one: True False

in demonstration of strong and weak electrolyte and non electrolytes a lightbulb apparatus that shows how much a solution conducts electricity by brightness of the light is often used. when pure water is tested the bulb does not light. when some acetic acid is added to the water the bulb burns dimly. when more acetic acid is added to the solution the bulb burns a little more brightly. if our acetic acid was used, what would be observed? a. the...
